An all-pass filter is a type of signal processing filter that allows all frequencies of input signals to pass through with equal gain but alters the phase relationship between various frequency components. In other words, it does not modify the amplitude of the signal but changes its phase. ### Key Characteristics of All-Pass Filters: 1. **Magnitude Response**: The magnitude of the output signal remains constant across all frequencies, typically set to 1 (0 dB).
